You managed to pack a lot of features in, I'm impressed. The leaderboard is a nice touch. :) It's a fun concept and feels good to play, I had fun playing. I like the risk/reward of the speed boosts, though I ended up going at a slower pace most of the time. The multipliers are very interesting, it took me a moment to figure out just how important they are for getting a high score.
This is not really relevant for the gameplay, but: Why eyeballs?
